+============================
+C-SKY Multi-processors Timer
+============================
+
+C-SKY multi-processors timer is designed for C-SKY SMP system and the
+regs is accessed by cpu co-processor 4 registers with mtcr/mfcr.
+
+ - PTIM_CTLR "cr<0, 14>" Control reg to start reset timer.
+ - PTIM_TSR "cr<1, 14>" Interrupt cleanup status reg.
+ - PTIM_CCVR "cr<3, 14>" Current counter value reg.
+ - PTIM_LVR "cr<6, 14>" Window value reg to triger next event.
+
+==============================
+timer node bindings definition
+==============================
+
+ Description: Describes SMP timer
+
+ PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: must be "csky,mptimer"
+ - clocks
+ Usage: required
+ Value type: <node>
+ Definition: must be input clk node
+ - interrupt
+ Usage: required
+ Value type: <u32>
+ Definition: must be timer irq num defined by soc
+ - interrupt-parent:
+ Usage: required
+ Value type: <node>
+ Definition: must be interrupt controller node
+
+Examples:
+---------
+
+ timer: timer {
+ compatible = "csky,mptimer";
+ clocks = <&dummy_apb_clk>;
+ interrupts = <16>;
+ interrupt-parent = <&intc>;
+ };
